I read your post on your grandfather and great grandfather. My father's name was Willis Allen Larance. His father was Wesley Howard Larance. My grandfather, Wesley Howard, was also from Hilly, Louisiana. My grandfather had a brother named Velmer Jahue Larance. My father was killed in action in WWII so I know very little about his side of the family. I just thought the similarities in the names were remarkable. I wish I had more information, but I am afraid I do not.
Good luck in your search.
